The size of the bonus depends on the number of people you send Empty Chalices to right before you send your Push Notifications. You will receive 1 bonus BT Pt for each person you send a notification to.

You will receive these bonus BT Pts regardless of whether or not your allies have Push Notifications disabled through their settings.

You can set whether or not you want to receive event-related Push Notifications via the main page of the event.

Alternatively, you can also adjust these settings via the Options tab found on the main page.

Bonus Units

The following units from the Dream Packs Season 80 and Three Step Packs 27 receive Bonuses to their HP, attack power and speed when they are deployed in Event Battles. They also earn bonus Empty Chalices based upon their rarity.
